Las Vegas, NV Mulberry Pollen
Mulberry pollen in Las Vegas usually peaks around March to April, reaching Moderate at its worst. Las Vegas planted so many olive and mulberry trees that their pollen became a public health problem, and Clark County banned new ones in 1991. Those trees still drive a heavy spring, with juniper in winter and grass into early summer.
Fruitless male mulberry trees release heavy, highly allergenic pollen in spring. Clark County banned planting new ones in 1991 alongside olive.

Managing mulberry season in Las Vegas
If mulberry is your trigger, start a daily antihistamine like cetirizine (Zyrtec) or loratadine (Claritin) a week or two before the March to April peak, rather than waiting for symptoms. Keep windows closed on high-count mornings, shower and change clothes after time outside, and run the AC on recirculate in the car.
When symptoms don't ease with over-the-counter medicine, an allergist in Nevada can test whether mulberry is really what you react to and talk through longer-term options like allergy shots.
